PIPE WRENCH AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 533,426, dated February 5, 1895.

Application filed June 18,1894. S rial 1%. 514,948. (No model.)

To aZZ whom it may concern.-

Be it known that 1, PETER BARTZEN, a citizen of the United States, residing at Huron, in the county of Erie and State of Ohio, have invented anew and useful Pipe Wrench and Gutter, of which the following is a specification.

The invention relates to improvements in pipe wrenches and cutters.

The object of the present invention is to improve the construction of combined pipe wrenches and cutters, and to provide a simple and inexpensive device, which will be easy of application, and which may be readily applied in any desired position, and capable of effectively gripping the pipe without liability of slipping and skinning the same.

A further object of the invention is to provide a wrench, which may be readily used as either a nut or pipe wrench, and which may be quickly adjusted to serve as a cutter.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings-Figure 1 is aperspective view of a combined cutter and pipe wrench, constructed in accordancewith this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. 4 is a detail perspective view of the detachable movable jaw. Fig, 5 is a similar view of the cutter.

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designatesa shank, having its lower or inner end formed into a handle, and provided at its upper end with an angular stationary jaw 2 provided at its outer extremity with a rectangular cutter socket 3. The shank is provided between its ends with an outward extending arm 4, arranged at right angles to the shank and provided with a threaded perforation 5, receiving an adjustment screw 6; and the latter'has its upper end swiveled by a screw 7 in the lower end or vertical socket 8 of a slide 9. The slide 9 is mounted on the Its inner portion is bifurcated for the reception of the shank, and the terminals of the sides formed by the bifurcation are connected by a screw 10, or similar fastening device. The adjusting screw is provided at its upper end with an annular groove for the reception of the inner end of the screw 7, and detachably secured in the upper end of the socket 8 is a shank 11 of a jaw 12, which is provided with shouldered teeth to engage the pipe, and whichslides on the shank. through the medium of the slide 9. The shank 11 is clamped in the upper end of the socket by the screw 13; and when it is desired to use the device as a nut wrench, the jaw 12 may be readily'removed. By turning the adjusting screw the desired grip may be readily obtained; and the wrench is thereby enabled to engage a pipe without liability of slipping and skinning the same.

The rectangular socket 3 of the stationary jaw receives a reversible cutter 14, which has its ends 15 beveled to divide cutting edges; and it is capable of ready adjustment in the socket, and is securely clamped by opposite screws 16 and 17 arranged in threaded perforations of the jaw. The perforations of the jaw communicate with the socket, so that the cutter is clamped at both front and rear; and the socket tapers slightly, so that the desired pitch of the cutter may be obtained.

It will be seen that the'wrench is simple and comparatively inexpensive in construction; that it is adapted to be readily arranged for operation, as a cutter, a pipe wrench, or a nut wrench; that it is capable of ready adjustment to suit different sizes of pipes or nuts; and that it securely grips apipe without liability of accidentally slipping.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle, or

sacrificing any of the advantages of this in- Vention.

What I claim is 1. The combination of a shank provided at its upper end with an angular stationary jaw and having at the outer extremity thereof a socket, a cutter arranged in the socket, screws mounted on the stationary jaw at the socket and engaging the cutter and securing the same in its adjustment, a slide mounted on the shank, and means for operating the same, substantially as described.

2. A pipe wrench "and cutter, comprising a shank, provided at its outer end with an angular stationary jaw terminating in a tapering rectangular socket, the cutter arranged in the socket, the adjusting screws 16 and 17 mounted at the inner and outer sides of the socket, and located at different points on the same, the rigid arm 4 extending outward from the shank intermediate of the ends thereof and provided with a threaded opening, the slide mounted on the shank between the stationary jaw and said arm, and provided with a vertical socket extending entirely through it, the detachable jaw 12 arranged on the upper face of the slide and having a shank secured in the upper end of the socket thereof, and the adj nsting screw passing through the opening of the arm and swiveled in the lower end of the socket of the slide, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

PETER BARTZEN.
